Photodissociation spectroscopy and ab initio calculations for the Sr+-N-2 complex
Electronic vibrationally resolved spectra of the Sr+-N-2 complex have been recorded in two energy regions 20 284-22 988 cm(-1) and 15 576-16 380 cm(-1). In the high energy region, two progressions are present and they are attributed to the (2)(2)Pi(3/2,1/2) <- X-2 Sigma(+) transitions assuming a linear molecule. This linear configuration is supported from the observed spin-orbit splitting of these excited states as well as from electronic structure calculations. The lower energy spectrum shows a structure, which ends up to a continuum. Considering the complex as an anharmonic oscillator, the spectroscopic constants and the dissociation energies of the corresponding states are determined. (C) 2010 Elsevier B.V. All rights reserved.
